T\u00edm m\u00edstem je povrch siln\u011b vulkanick\u00e9ho Jupiterova m\u011bs\u00edce Io<\/a>.<\/p>\n

Kdybyste se na tomto m\u011bs\u00edci postavili a\u00a0zvedli hlavu, naskytl by se v\u00e1m pohled, kter\u00fd lidsk\u00fd mozek jen st\u011b\u017e\u00ed dok\u00e1\u017ee zpracovat.

Smrtelnou d\u00e1vku byste utr\u017eili b\u011bhem n\u011bkolika m\u00e1lo sekund.<\/p>\n

Kdy\u017e se va\u0161e t\u011blo vzd\u00e1 bez boje<\/p>\n

V\u011bt\u0161ina lid\u00ed si smrt ve voln\u00e9m vesm\u00edru p\u0159edstavuje bu\u010f jako pomal\u00e9 udu\u0161en\u00ed z\u00a0nedostatku kysl\u00edku, nebo jako dramatickou explozi v\u00a0d\u016fsledku n\u00e1hl\u00e9 dekomprese.

Abychom pln\u011b pochopili, co by v\u00e1s na povrchu m\u011bs\u00edce Io b\u011bhem vte\u0159iny zabilo, mus\u00edme se pod\u00edvat hluboko pod povrch samotn\u00e9ho Jupiteru.<\/p>\n

Pomozme si jednoduchou analogi\u00ed. P\u0159edstavte si obrovsk\u00fd, rychle rotuj\u00edc\u00ed magnet uprost\u0159ed kovoobr\u00e1b\u011bc\u00ed tov\u00e1rny pln\u00e9 drobn\u00fdch \u017eelezn\u00fdch pilin.

P\u0159edstavte si svou DNA jako obrovskou, pe\u010dliv\u011b sepsanou knihu s\u00a0detailn\u00edm n\u00e1vodem, jak m\u00e1 va\u0161e t\u011blo fungovat. Pokud do takov\u00e9 knihy ob\u010das zd\u00e1lky vyst\u0159el\u00edte z\u00a0brokovnice (co\u017e p\u0159edstavuje b\u011b\u017en\u00e1, pozemsk\u00e1 radiace), text se sice trochu po\u0161kod\u00ed, ale va\u0161e t\u011blo m\u00e1 uvnit\u0159 bun\u011bk \u0161ikovn\u00e9 \u00fadr\u017eb\u00e1\u0159e (opravn\u00e9 enzymy).

Kdy\u017e ale stoj\u00edte na povrchu Io, je to, jako byste tu samou knihu hodili p\u0159\u00edmo do pr\u016fmyslov\u00e9ho drti\u010de odpadu. Radiace je zde natolik extr\u00e9mn\u00ed, \u017ee vysokoenergetick\u00e9 \u010d\u00e1stice doslova rozt\u0159\u00ed\u0161t\u00ed va\u0161e \u0159et\u011bzce DNA na miliardy nepou\u017eiteln\u00fdch kousk\u016f b\u011bhem zlomku vte\u0159iny.<\/p>\n

D\u00e1vka radiace, kterou byste na povrchu m\u011bs\u00edce Io obdr\u017eeli za jedin\u00fd den, p\u0159ekra\u010duje absolutn\u00ed smrtelnou d\u00e1vku pro \u010dlov\u011bka v\u00edce ne\u017e tis\u00edckr\u00e1t.
